I IMPROVED REFRIGERATOR The Schedule referred to in these Letter! Patent and making part of the same.

To all whom it may concern:

Be it known that I, MORGAN BURTON, of Darlington, in the county of Beaver, and State of Pennsylvania, have invented certain new and useful Improvements in Combined Refrigerator, \Vat 1-0ooler, and

Ice-Cream Freezer; and do hereby declare that the with a saline mixture, which takes the place of ice.

The accompanying drawing represents a perspective of my invention.

Letter A represents a vessel, of any desired shape or size, and which may be constructed of wood, tin, iron, copper, or any suitable material.

Inside of this vessel there is placed a smaller one, B, of similar shape and construct-ion, having a space left between them on every side, except the top, and which is provided with a double or hollow-cover, c.

In this space I place a saline mixture, consisting of eleven (11) parts common salt, and one (1) part saltpetre, slightly moistened, or entirely dissolved in water, which takes the place of ice, and which freezes the articles placed in the inner chamber B, much morereadily and quickly than the ice.

Through that part of the frame which covers the space between the two vessels, on top, there is a number of openings made, so as to admit the air to the mixture, which is carried downward by small tubes (1, shown by dotted lines, which may extend from two-thirds to three-fourths of the depth of the space,'and which also serve to discharge the vitiated air and gas.

Over these openings there is placed a spigot, 1), by means of which the quantity of air admitted by the tube can be regulated at will, and through which the mixture may be drawn off, when it is desirable to renew it.

For ice-cream, or any substance which may require a quick process of cooling, the inner vessel B should be round, so as to facilitate revolution.

In the top of the cover c, there is also an opening made, through which the saline mixture is introduced, so that it maybe upon every side of the inner vessel B.

Having-thus described my invent-ion,

. What I-claim, and desire to secure by Letters Putent, is-

The combination of the vessels A B, with intervening space between, pipes a- (1-, spigot D, and hollow cover 0, all substantially as and for the purposes setforth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 17th day of July, 1869.

MORGAN BURTON.
